Prayer Circles

My son seems to be bitter and angry at the world because he has been hurt so many times by women. He is 29 years old and wants to have a serious relationship and have a family, I tell him he is settling just to have someone, because he is so insecure and has no confidence because of his weight problem. I have tried to persuade him to join a gym but he doesn't have much enthusiasium. I pray he will do something soon to change the way things are. I worry so much that he will not find happiness, but first he must find it in himself.
